python argument parser example

Command-line arguments are a powerful way to interact with your Python scripts, allowing users to customize the script's behavior without modifying the code. The argparse module in Python provides a convenient way to parse command-line arguments. In this tutorial, we'll explore the basics of using argparse with a practical code example.
The first step is to import the argparse module in your Python script. This module simplifies the process of parsing command-line arguments.
Next, create an ArgumentParser object. This object will hold all the information necessary to parse the command-line arguments.
The description parameter is optional and provides a brief description of what the script does.
Now, let's add some arguments to our parser. For this example, we'll add a simple argument that takes an integer value.
Here:
Once you've added all the desired arguments, call the parse_args() method to parse the command-line arguments.
The parsed arguments will be stored in the args variable.
You can now access the values of the parsed arguments using dot notation on the args object.
Here's the complete code for our example:
You should see the output:
Feel free to customize and extend this example to suit your specific needs. The argparse module provides many options for handling different types of arguments and generating helpful usage messages.
